Records assembled by David Grenville relating to two projects on Omond McKillop Solandt: a proposed biography of him (never completed) and a symposium in his honour (1994) that was published as Perspectives in science and technology: the legacy of Omond Solandt. The files for the biography include original documents, research notes, correspondence, notes, manuscripts and addresses by Solandt (1957-1980) and 66 audio cassette tapes (with tape summaries by Jason Ridler) of interviews Grenville did with Solandt and his colleagues. The files on the symposium contain correspondence, minutes of meetings, notes, financial records, and partial drafts and copies of the book. There are also a number of accompanying photographs.
